About this study

The main purpose of this study is to learn more about the safety, side effects, and effectiveness of Vepugratinib by itself or when it is combined with other medicines that treat cancer. Vepugratinib may be used to treat cancer of the cells that line the urinary system and other solid tumor cancers that have a change in a particular gene (known as the FGFR3 gene). Study participation could last up to approximately 6 years, depending on which part of the study you join.

Sponsor: Eli Lilly and Company
